Definitions

  • the present invention relates to a method for operating an electromechanically actuated and / or electromechanically lockable parking brake for motor vehicles, which are supplied essentially from an operating element, an electronic control unit, the wheel speed of wheel speed sensors, at least one unit for generating a clamping force and mechanically lockable braking devices at least one axis, wherein the braking devices are zuspannbar by the unit.
  • the invention relates to a parking brake for motor vehicles for carrying out the method.
  • a parking brake for motor vehicles which provides at least two wheel brakes each having an actuator which zuspannt the wheel brake associated therewith by means of a cable.
  • a method for actuating a parking brake is known from the cited document, according to which the application force of the actuator depends on the speed of the motor vehicle and also prevents blocking of the wheels braked by the actuator.
  • the method without wheel speed values which both represent the speed of the motor vehicle and also disclose a possible blocking of the wheels braked by the actuator, is not feasible.
  • German Offenlegungsschrift DE 198 36 687 A1 discloses an electronic parking brake system and a method for its operation.
  • the vehicle speed of the electronic parking brake system is supplied as an input signal to determine the driving situation of the motor vehicle.
  • the disclosed method can not be performed.
  • the present invention is therefore based on the object to represent a method for operating an electromechanical parking brake for motor vehicles, which works reliably in the absence of wheel speed values, so that the driving behavior of the motor vehicle for the driver remains manageable.
  • This object is achieved procedurally in that the parking brake is activated after activation in the absence of wheel speed values in a first operating mode, provided that the braking devices are not clamped, while the parking brake is otherwise activated in a second operating mode.
  • the parking brake is activated in a first operating mode, if already missing wheel speed values were detected in the previous operating interval.
  • the parking brake is activated in a first operating mode, unless the driver of the parking brake assigns the second operating mode.
  • An advantageous development provides that the parking brake is activated in a second operating mode when the driver turns off the ignition and operates the control element for longer than a predetermined period of time.
  • the parking brake is activated in a second operating mode when the vehicle driver switches off the ignition and removes the ignition key from the ignition lock for at least a predetermined period of time.
  • the application force of the parking brake in the first operating mode is constructed and maintained exclusively during the operation of the control element and that the parking brake is applied in the second operating mode upon actuation of the control element with maximum allowable force, with a release only by means of renewed Operation of the control element is possible with the ignition switched on.
  • the object is achieved in that means are provided which control the parking brake after activation in case of missing wheel speed values in a first operating mode, if the braking devices are not clamped, while the parking brake is otherwise activated in a second operating mode.
  • a control lamp is provided which informs the driver whether the parking brake is activated in the first or in the second operating mode.
  • Fig. 1 is a circuit diagram of a hydraulic brake system is shown schematically.
  • the hydraulic brake system has on a first axis, the front axle, wheel brakes 2, which are acted upon during service braking via a hydraulic line 9 with pressure.
  • the wheels of the front axle are assigned wheel speed sensors 12 whose output signals are fed to an electronic control and regulation unit (ECU) 5.
  • ECU electronic control and regulation unit
  • This electronic control unit 5 is assigned to the service brake system.
  • the rear axle, wheel brakes 3 are also provided, which can be acted upon during service braking via a second hydraulic line 10 with pressure.
  • the wheel speeds of the wheels of the rear axle are determined by wheel speed sensors 13 and the aforementioned electronic Control and regulating unit 5 supplied.
  • the wheels of the rear axle in addition to the wheel brakes 3 for service braking on an electromechanical parking brake.
  • the electromechanical parking brake has two mechanically lockable braking devices 4, which are designed as drum brakes 4, each with an expanding lock, not shown, on.
  • the aforementioned expansion lock can be actuated by means of a cable 11 of an electromechanical actuator 1, after which the drum brakes 4 are applied.
  • a parking brake operation is performed after the operation of a control element 7 by the driver.
  • the output signals of the control element 7 of the electromechanical parking brake associated electronic control unit (ECU) 6 are supplied, which controls the already mentioned electromechanical actuator 1 accordingly.
  • the aforementioned electronic control unit 6 and the electronic control unit 5 associated with the service brake system communicate with each other via a data line 8, which is designed as a CAN connection.
  • the drum brakes must be 4 while driving the motor vehicle zuspannbar to provide the driver after a possible failure of the service brake system emergency braking function.
  • the electromechanical parking brake is actuated in two different operating modes, a dynamic and a static operating mode.
  • the drum brakes 4 are completely tightened by means of the electromechanical actuator 1 upon actuation of the operating element 7 by the vehicle driver and maintain this application force.
  • the electromechanical actuating unit 1 has a non-illustrated self-locking gear. A suspension the applied application force is possible only by means of a renewed actuation of the control element 7 with simultaneously switched ignition. This braking behavior is referred to below as the second or static operating mode of the electromechanical parking brake.
  • the drum brakes 4 are only clamped and the applied application force maintained as the driver actuates the operating element 7. As soon as the driver no longer actuates the operating element 7, the motor vehicle is again in an unrestrained state.
  • This braking behavior of the electromechanical parking brake is referred to below as the first or as a dynamic operating mode. If the electromechanical parking brake is activated in the dynamic operating mode, then it is not possible to park the motor vehicle with the aid of the electromechanical parking brake.
  • Missing signals of the wheel speed sensors 12, 13 or Interrupted data line 8 are the parking brake associated electronic control unit 6 no Radfiere warmth more available and the electronic control unit 6 is on actuation of the control element 7 by the driver no decision criterion available whether the parking brake is to be controlled in the static or dynamic operating mode.
  • the inventive method provides that the electromechanical parking brake is driven in the absence of wheel speed values except for the exceptions below in the dynamic operating mode.
  • the driver is this state mediated by a mounted in the field of fittings lamp 17 which flashes constantly.
  • the aforementioned lamp 17 is connected via a separate line with the parking brake associated electronic control unit 6 so that the information of the driver regardless of a possible failure of the data link 8 between the two electronic control and regulation units 5, 6 is.
  • a schematically indicated ignition lock 27 is also connected via a separate line with the parking brake associated electronic control unit 6 and information is transmitted whether the ignition key is in the ignition 27 and whether the ignition is on or off.
  • the electromechanical parking brake is put into operation, inter alia, by switching on the ignition.
  • the electromechanical parking brake is activated in the event of missing wheel speed values in the dynamic operating mode, unless one of the following exceptions applies.
  • the operating mode of the electromechanical parking brake is not dynamic, provided that the drum brakes after commissioning the electromechanical parking brake 4 are applied, that is, if the measured by a sensor not shown load of the cable runs 11 is greater than a force of 100 N.
  • the electromechanical parking brake is also not driven in the dynamic operating mode in the absence of wheel speed values, if after the electromechanical parking brake has been put into operation no indication of missing wheel speed values in the previous operating interval has been stored in one of the two electronic control and regulation units 5, 6. In this case, it is assumed for a predetermined period of time that the motor vehicle actually stops and is put into operation from the safely parked state. If the electronic control unit 6 is still not supplied with any wheel rotational speed values after expiry of the previously mentioned predetermined period of time, then the electromechanical parking brake is actuated in the dynamic operating mode.
  • the electromechanical parking brake is not driven in the absence of wheel speed values in the dynamic operating mode when the driver selects the static mode of operation.
  • the choice of the driver is made by an actuation of the control element 7 after the driver has turned off the ignition.
  • Fig. 2 which represents the actuation time t of the operating element 7 by the driver and on the ordinate the applied by the electromechanical actuator 1 load of the cable 11 on the abscissa, is illustrated as the driver from the dynamic to static operating mode of the electromechanical parking brake can change.
  • the load of the cable runs 11 before the operation of the control element 7 is almost zero.
  • the load of the cable runs 11 is immediately increased to the maximum permissible value, which is shown in FIG. 2 with the aid of the position 24. With this sudden increase in cable load the driver is taught that the operating mode will change from dynamic to static, if he continues to operate the control element 7.
  • the electromechanical parking brake is also not driven in the dynamic mode of operation when the vehicle operator shuts off the ignition and the last wheel speed values received by the electronic control unit 6 are indicative of a vehicle speed of less than 10 km / h. This fact indicates that the driver wants to park his car after switching off the ignition. For this reason, the electromechanical parking brake is controlled under the conditions just described in the static operating mode.
  • the operating mode of the electromechanical parking brake changes from dynamic to static when the vehicle operator shuts off the ignition and removes the ignition key from the ignition lock 27 mentioned in connection with FIG. 1 for a predetermined period of preferably 100 msec.
  • the drum brakes 4 are completely tightened by means of the electromechanical actuating unit 1 and maintain this application force. If the ignition key is reintroduced into the ignition lock 27 before the control element 7 is actuated, the electromechanical parking brake is actuated again in the dynamic operating mode.
  • a control lamp 17 is provided, which is connected directly to the electromechanical parking brake associated electronic control unit 6.
  • the pilot lamp 17 keeps flashing.
  • the control element 7 so the drum brakes 4 are completely tightened as already mentioned with the help of the electromechanical actuator 1 and maintain this application force. The thus possible, safe parking of the vehicle is displayed to the driver by a constant lighting of the above-mentioned control lamp.
